RE: Big servo for use in Elevator Trim Tab Ultralight Airplane
Strange, we used your, 'non indicator type' through WWII and much of Korea on trim tabs.
We were so dumb we were happy when we felt what it was we were after . No indicators needed !
Apparently we had much more sensitive 'arses' then .
BTW, UAV's like RC models have no passengers soooo I really do not feel that is is anything of note .
Today the FAA calls them sUAS .
